Having a variety of ways to play is great for the health of a game, and while obvious favourites will emerge, like Constructed, its only a matter of time before we start seeing things like Willpower and Poorcana (the common-only Pauper-inspired format) pick up more traction too
This works because your token copies all enter as 1/1 creatures, which makes your ERB creatures all the more valuable
Each opponent losing three life per combat is not insignificant, but also not exactly game-ending unless youve got ways to crank out multiple combats
This matchup is the main reason I decided to just play the 4th Grasp main deck as its the best answer to Glorybringer and dealing with Whirler Virtuoso/Bristling Hydra with their ETB triggers on the stack (if they dont already have 3 Energy of course)
As such, the Oracle text on Hostage Taker has since been changed to say exile ANOTHER target creature until Hostage Taker leaves the battlefield
It ETBs with energy, sure, but it can convert energy to creatures without tapping, which, of course, means you can generate infinite tokens pretty easily with the other cards here
